The effect of functional morphemes on word segmentation in preverbal infants

This study examines the role of functional morphemes in the earliest stage of lexical development. Recent research showed that prelinguistic infants can perceive functional morphemes. We inquire whether infants use frequent functors to segment potential word forms. French-learning 8-month-olds were familiarized to two utterance types: a novel noun following a functor, and another novel noun following a prosodically matched nonsense functor. After familiarization, infants' segmentation of the two nouns was assessed in a test phase presenting the nouns in isolation. Infants in Experiment 1 showed evidence of using both frequent functors des and mes (as opposed to the nonsense functor kes) to segment the nouns, suggesting also that they had specific representations of the functors. The infrequent functor vos in Experiment 2 did not facilitate segmentation. Frequency is thus a crucial factor. Our findings demonstrate that frequent functors can bootstrap infants into early lexical learning. Furthermore, the effect of functors for initial word segmentation is likely universal.

妈妈与女儿的对话

女儿：中国地质大学大一学生 妈妈：中国无神论学会理事 女儿：妈妈,我的辅导员向我介绍了一本书《心灵的自救》（peace in mind）。据说它在美国畅销了50多年。现在国内也很热销。我觉得它特别符合我的想法,好像它解决了我好多关于人生、对社会的看法问题。所以我想让它成为手边书,能经常参照着做。     

模糊容忍性：研究回顾、现状与展望

模糊容忍性是个体或群体面对一系列不熟悉的、复杂的、或不一致的线索时,对模棱两可的环境刺激信息进行知觉和加工的方式。基于国内外相关研究,文章回顾了模糊容忍性的概念界定和研究历史,认为当前研究现状集中于模糊容忍性的测量及其与组织、文化、个体认知和其他人格变量之间的关系方面。其中,模糊容忍性与创造性的关系尤其值得关注。文章据此给出了未来开展该领域研究的几点建议。

8岁到成年期工作记忆广度的发展

工作记忆与认知能力、智力和学习能力有密切的联系.本研究采用横断研究的方法,测量了213名8岁到成年期被试的数字、词语和视空间工作记忆广度,探查了工作记忆广度的发展情况.结果发现,数字工作记忆广度在此期间持续增长,词语广度在18岁达到最高,视空间工作记忆广度在14-16岁达到高峰.不同任务的工作记忆广度具有相似的发展趋势,但工作记忆的平均广度分数与Pascual-Leone模型的预测并不一致.

French‐learning toddlers use gender information on determiners during word recognition

In gender‐marking languages, the gender of the noun determines the form of the preceding article. In this study, we examined whether French‐learning toddlers use gender‐marking information on determiners to recognize words. In a split‐screen preferential looking experiment, 25‐month‐olds were presented with picture pairs that referred to nouns with either the same or different genders. The target word in the auditory instruction was preceded either by the correct or incorrect gender‐marked definite article. Toddlers’ looking times to target shortly after article onset demonstrated that target words were processed most efficiently in different‐gender grammatical trials. While target processing in same‐gender grammatical trials recovered in the subsequent time window, ungrammatical articles continued to affect processing efficiency until much later in the trial. These results indicate that by 25 months of age, French‐learning toddlers use gender information on determiners when comprehending subsequent nouns.     

The effects of subthreshold synchrony on the perception of simultaneity

We aimed to examine the effects of subthreshold synchrony and asynchrony on the perception of simultaneity. We rendered simultaneous or asynchronous luminance changes below detection thresholds by embedding them in a sequence of rapidly onsetting flankers. Still, simultaneity of subthreshold luminance changes can influence decisions concerning the simultaneity of clearly visible changes in luminance: across a range of very brief target SOAs, subthreshold synchrony was found to increase the tendency to report ‘simultaneity’, although simultaneity thresholds themselves remained largely uninfluenced. These effects are discussed in terms of the early synchronization of sensory mechanisms and the extent to which this pattern of synchronization influences the perception of relations between events in time.
